I suddenly find myself owning 1970 4-cylinder 2.4 with Web hot street Cam idles nicely and pulls hard at WOT. Part throttle response is not great, often with carbs coughing and even backfiring on trailing throttle. My use is mostly street, so I'd like to get this part throttle stuff sorted.
Here's pictures of the stuff that's in there now. I guess that's the infamous Bosch 009 with no vacuum advance and a PerTronix 1847A. The carbs are Dellorto DRLA 45s with short velocity stacks and these tall foam things that don't seal against the air cleaner housings. I'm willing to learn about the carbs but I don't have much confidence in the 009 for running nicely on the street. Please correct me if I'm wrong about any of this stuff. Also from other threads I gather that switching to EFI such as MicroSquirt would cost $5K or so ... though I'm not ruling this out completely. Correct me if I'm wrong about that. Is this kind of linkage OK? Here's the idle you may have seen in another post: https://www.youtube.com/watch?v=-AC53RRrXOU Any help you can provide is appreciated! --Michael in Seattle |

Sorry but just want to make sure all the facts are there You are running premium gasoline ? Correct I think so. Previous owner said he was. I finally saw the low fuel light yesterday and filled it with 92. I didn't ever hear anything resembling pinging. In Arizona both my 914s pinged a lot unless I retarded the timing so far the cars were slow. |
